Hey how we doing tonight I got a question, a local guy has a newer style re xxx15 in nice shape and I got two sa12's layimg around im gonna trade him for it. Now I know alot of you will say it's a ****** sub and what not but I can always sell it on local craiglist for what I got in my sa's if need be, now that thats said should I do a large sealed box or a ported box? I heard they do really good in a huge sealed box. I'll be running around 2.5k to it as well any advice is appreciated
